CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation in part of International Patent Application PCT No. PCT/CN2014/091812, filed on Nov. 20, 2014, entitled “MULTI-SYSTEM TERMINAL SYSTEM UPDATING METHOD, UPDATING DEVICE AND TERMINAL”, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the technical field of terminal system, and in particular, to a system updating method for a multi-system terminal, a system updating device for a multi-system terminal, and a terminal.

BACKGROUND

With the development of smart terminal technology, the pertinent art provides terminals having multiple systems. For example, for a terminal having two systems, one system is used as a safe system, and the other system is used as a normal system.

Presently, many manners of running dual systems of a terminal exist. For example, each time just one system is run, and when switching the systems, the terminal needs to be restarted. Or the two systems are run simultaneously, and a certain manner can be used for switching the two systems without restarting the terminal. During a process of using the dual-system terminal, a problem of updating systems of the multi-system terminal inevitably occurs. However, in the pertinent art, a feasible system updating solution for the multi-system terminal is not proposed.

Therefore, how to update systems of the multi-system terminal has become a technical problem which needs to be solved instantly.

SUMMARY

Based on at least one of the above technical problems, the present disclosure provides a new system updating solution for a multi-system terminal. By means of the present disclosure, any system of the multi-system terminal can be simply updated, a high applicability can be obtained, and the operation and control is easy, thereby improving efficiency of system updating.

In view of this, in the present disclosure, a system updating method for a multi-system terminal is provided. The method comprises: during a process of creating a system updating file of the multi-system terminal, detecting whether data of a plurality of file partitions specified in the system updating file has changed; upon detecting that the data of at least one file partition of the plurality of file partitions has changed, establishing an identification file for updating a system corresponding to the at least one file partition in the system updating file; and upon receiving an instruction for updating a system of the multi-system terminal, updating a corresponding system of the multi-system terminal according to the identification file of the system updating file.

In the technical solution, when updating a system of the terminal, what is needed to do is to add a patch file to a corresponding file partition of the system updating file. Therefore, during the process of creating the system updating file, when it is detected that the data of the multiple file partitions specified in the system updating file has changed, the multi-system terminal establishes an identifier file for updating a corresponding system, thus the system to be updated can be determined during the process of creating the patch file. Accordingly, when the multi-system terminal performs an operation of system updating, a corresponding system of the multi-system terminal can be updated just according to the identifier file of the system updating file, and a user does not need to participate in the system updating process to inform the terminal of the system to be updated, accordingly, any system of the multi-system terminal can be easily updated, a high applicability can be obtained, the operation and control is easy, thereby improving efficiency of system updating.

In the above technical solution, preferably, the plurality of file partitions comprises a partition of a boot program for booting the loading of a kernel of the multi-system terminal. Detecting whether the data of the plurality of file partitions specified in the system updating file has changed, and establishing the identifier file comprises: detecting whether the data of the partition of the boot program for booting the loading of the kernel of the multi-system terminal has changed; and establishing the identifier file for updating all systems of the multi-system terminal upon detecting that the data of the partition of the boot program for booting the loading of the kernel of the multi-system terminal has changed.

In the technical solution, the partition of the boot program for booting the loading of the kernel of the terminal is a partition which needs to be firstly loaded when the terminal is started. If the data of the partition has changed, it indicates that a system loading strategy of the terminal has changed, thus each of the systems of the terminal needs to be updated. For example, for an embedded system, e.g., the Android system, the boot program for booting the loading of the kernel of the terminal is bootloader, the partition of the boot program is an aboot partition. When it is detected that the data of the aboot partition of the system updating file has changed, it is determined that all of the systems of the terminal need to be updated.

In the above technical solution, preferably, the plurality of file partitions further comprise partitions of boot programs each for booting the starting of one of the systems of the multi-system terminal, and system partitions each corresponding to one of the systems. Detecting whether the data of the plurality of file partitions specified in the system updating file has changed, and establishing the identifier file comprises: detecting whether the data of the file partitions of the boot programs each for booting the starting of one of the systems of the multi-system terminal has changed, and detecting whether the data of the system partitions each corresponding to one of the systems has changed; and upon detecting that the data of the partition of the boot program for booting the loading of the kernel of the multi-system terminal is unchanged, and detecting that the data of the partition of the boot program for booting the starting of one of the systems of the multi-system terminal has changed, and/or upon detecting that the data of the system partition corresponding to the one of the systems has changed, establishing an identifier file for updating the one of the systems.

In the technical solution, the partition of the boot program for booting the starting of one of the systems and the system partition corresponding to the one of the systems correspond to the one of the systems of the terminal. Therefore, upon detecting that the data of the partition of the boot program for booting the one of the systems has changed, and/or upon detecting that the data of the system partition corresponding to the one of the systems has changed, it is determined that the one of the systems needs to be updated. For example, in the Android system, the partition of the boot program for booting the starting of one of the systems is the boot partition, and the system partition corresponding to one of the systems is the system partition. Upon detecting that in the system updating file the data of the boot partition corresponding to a certain system has changed, and/or upon detecting that in the system updating file the data of the system partition corresponding to the certain system has changed, it is determined that the certain system needs to be updated.

In the above technical solution, preferably, upon receiving the instruction for updating a system of the multi-system terminal, the method further comprises: parsing the system updating file to obtain the identifier file of the system updating file.

In the technical solution, after creating the system updating file, the system updating file is compressed. Thus, when determining whether the system updating file includes the identifier file for updating a system of the terminal, the system updating file needs to be parsed.

In the above technical solution, preferably, whether the data of each of the plurality of file partitions has changed is determined by detecting whether each of the plurality of file partitions comprises a file having a specified suffix.

Specifically, in the Android system, if the data of a certain partition of the system updating file has changed, a corresponding “*.P” patch file is created in the certain partition, thus whether the data of the file partition has changed can be determined by detecting whether the file partition includes a file having the specified suffix.

In the above technical solution, preferably, updating one of the systems of the multi-system terminal comprises: verifying in the system updating file files of the system partition of the one of the systems, and verifying in the system updating file the data of the partition of the boot program for booting the starting of the one of the systems; and after the verification, writing the files of the system partition of the one of the systems in the system updating file and the data of the partition of the boot program for booting the starting of the one of the systems in the system updating file into corresponding file partitions of the multi-system terminal respectively.

The system starting solution of the multi-system terminal of the present disclosure includes following.

According to an implementation of the present disclosure, upon receiving an instruction for starting all of the systems of the multi-system terminal, the partitions of the boot programs each for booting the starting of one of the systems of the multi-system terminal are loaded via the boot program for booting the loading of the kernel of the multi-system terminal. Scripts of init processes each corresponding to one of the systems are parsed via the init processes started by the kernel of the multi-system terminal, so as to create file systems each corresponding to one of the systems, and start system processes each corresponding to one of the systems, thereby realizing loading of the system partitions each corresponding to one of the systems.

Specifically, for a dual-system terminal, one system is defined as an unsafe system, and another system is defined as a safe system. After the terminal is powered on, the boot_unsafe partition and the boot_safe partition are simultaneously loaded by the bootloader of the terminal, and the init processes are started to respectively parse the scripts of the init_unsafe and init_safe, so as to create the file systems each corresponding to one of the systems, start the system processes, and so on. Therefore, the system_unsafe partition and the system_safe partition can be loaded to finish the starting of the dual-system terminal.

According to another aspect of the present disclosure, a system updating device for a multi-system terminal is further provided. The device comprises: a detecting unit configured to detect whether data of a plurality of file partitions specified in a system updating file has changed during a process of creating the system updating file of the multi-system terminal, an establishing unit configured to establish an identification file for updating a system corresponding to at least one file partition of the plurality of file partitions in the system updating file when the detecting unit detects that the data of the at least one file partition has changed, and a system updating unit configured to update a corresponding system of the multi-system terminal according to the identification file of the system updating file upon receiving an instruction for updating a system of the multi-system terminal.

In the technical solution, when updating a system of the terminal, what is needed to do is to add a patch file to a corresponding file partition of the system updating file. Therefore, during the process of creating the system updating file, when it is detected that the data of the multiple file partitions specified in the system updating file has changed, the establishing unit establishes an identifier file for updating a corresponding system, thus the system to be updated can be determined during the process of creating the patch file. Accordingly, when the system updating unit performs an operation of system updating, a corresponding system of the multi-system terminal can be updated just according to the identifier file of the system updating file, and a user does not need to participate in the system updating process to inform the terminal of the system to be updated, accordingly, any system of the multi-system terminal can be easily updated, a high applicability can be obtained, the operation and control is easy, thereby improving efficiency of system updating.

In the above technical solution, preferably, the plurality of file partitions comprises a partition of a boot program for booting the loading of a kernel of the multi-system terminal. The detecting unit is configured to detect whether the data of the partition of the boot program for booting the loading of the kernel of the multi-system terminal has changed. The establishing unit is configured to establish the identifier file for updating all systems of the multi-system terminal when the detecting unit detects that the data of the partition of the boot program for booting the loading of the kernel of the multi-system terminal has changed.

In the technical solution, the partition of the boot program for booting the loading of the kernel of the terminal is a partition which needs to be firstly loaded when the terminal is started. When the data of the partition has changed, it indicates that a system loading strategy of the terminal has changed, thus each of the systems of the terminal needs to be updated. For example, for an embedded system, e.g., the Android system, the boot program for booting the loading of the kernel of the terminal is bootloader, the partition of the boot program is an aboot partition. When it is detected that the data of the aboot partition of the system updating file has changed, it is determined that all of the systems of the terminal need to be updated.

In the above technical solution, preferably, the plurality of file partitions further comprise partitions of boot programs each for booting the starting of one of the systems of the multi-system terminal, and system partitions each corresponding to one of the systems. The detecting unit is further configured to detect whether the data of the partitions of the boot programs each for booting the starting of one of the systems of the multi-system terminal has changed, and detect whether the data of the system partitions each corresponding to one of the systems has changed. The establishing unit is further configured to establish an identifier file for updating one of the systems when the detecting unit detects that the data of the partition of the boot program for booting the loading of the kernel of the multi-system terminal is unchanged, and detects that the data of the partition of the boot program for booting the starting of the one of the systems of the multi-system terminal has changed, and/or detects that the data of the system partition corresponding to the one of the systems has changed.

In the technical solution, the partition of the boot program for booting the starting of one of the systems and the system partition corresponding to the one of the systems correspond to the one of the systems of the terminal. Therefore, upon detecting that the data of the partition of the boot program for booting one of the systems has changed, and/or upon detecting that the data of the system partition corresponding to the one of the systems has changed, it is determined that the one of the systems needs to be updated. For example, in the Android system, the partition of the boot program for booting the starting of one of the systems is the boot partition, and the system partition corresponding to one of the systems is the system partition. Upon detecting that in the system updating file the data of the boot partition corresponding to a certain system has changed, and/or upon detecting that in the system updating file the data of the system partition corresponding to the certain system has changed, it is determined that the certain system needs to be updated.

In the above technical solution, preferably, the device further comprises a first parsing unit configured to parse the system updating file to obtain the identifier file of the system updating file.

In the technical solution, after creating the system updating file, the system updating file is compressed. Thus, when determining whether the system updating file includes the identifier file for updating a system of the terminal, the system updating file needs to be parsed.

In the above technical solution, preferably, the detecting unit is configured to detect whether the data of each of the plurality of file partitions has changed by detecting whether each of the plurality of file partitions comprises a file having a specified suffix.

Specifically, in the Android system, if the data of a certain partition of the system updating file has changed, a corresponding “*.P” patch file is created in the certain partition, thus whether the data of the file partition has changed can be determined by detecting whether the file partition includes a file having the specified suffix.

In the above technical solution, preferably, the system updating unit comprises: a verifying unit configured to verify in the system updating file files of the system partition of the one of the systems, and verifying in the system updating file the data of the partition of the boot program for booting the starting of the one of the systems; and a writing unit configured to write the files of the system partition of the one of the systems in the system updating file and the data of the partition of the boot program for booting the starting of the one of the systems in the system updating file into corresponding file partitions of the multi-system terminal respectively after the verifying unit finishes the verification.

According to an implementation of the present disclosure, the system updating device for a multi-system terminal further includes: a loading unit configured to load the partitions of the boot programs each for booting the starting of one of the systems of the multi-system terminal via the boot program for booting the loading of the kernel of the multi-system terminal upon receiving an instruction for starting all of the systems of the multi-system terminal, and a second parsing unit configured to parse scripts of init processes each corresponding to one of the systems via the init processes started by the kernel of the multi-system terminal, so as to create file systems each corresponding to one of the systems, and start system processes each corresponding to one of the systems, thereby realizing loading of the system partitions each corresponding to one of the systems.

Specifically, for a dual-system terminal, one system is defined as an unsafe system, and another system is defined as a safe system. After the terminal is powered on, the boot_unsafe partition and the boot_safe partition are simultaneously loaded by the bootloader of the terminal, and the init processes are started to respectively parse the scripts of the init_unsafe and init_safe, so as to create the file systems each corresponding to one of the systems, start the system processes, and so on. Therefore, the system_unsafe partition and the system_safe partition can be loaded to finish the starting of the dual-system terminal.

However, the present disclosure may also be implemented by adopting other manners different from those described herein. Accordingly, the protection scope of the present disclosure is not limited by the specific implementations disclosed below.

As illustrated by FIG. 1, a system updating method for a multi-system terminal in accordance with an implementation of the present disclosure includes: step 102, during a process of creating a system updating file of the multi-system terminal, detecting whether data of multiple file partitions specified in the system updating file has changed; step 104, upon detecting that the data of at least one file partition of the multiple file partitions has changed, establishing an identification file for updating a system corresponding to the at least one file partition in the system updating file; step 106, upon receiving an instruction for updating a system of the multi-system terminal, updating a corresponding system of the multi-system terminal according to the identification file of the system updating file.

In the technical solution, when updating a system of the terminal, what is needed to do is to add a patch file to a corresponding file partition of the system updating file. Therefore, during the process of creating the system updating file, when it is detected that the data of the multiple file partitions specified in the system updating file has changed, the multi-system terminal establishes an identifier file for updating a corresponding system, thus the system to be updated can be determined during the process of creating the patch file. Accordingly, when the multi-system terminal performs an operation of system updating, a corresponding system of the multi-system terminal can be updated just according to the identifier file of the system updating file, and a user does not need to participate in the system updating process to inform the terminal of the system to be updated, accordingly, any system of the multi-system terminal can be easily updated, a high applicability can be obtained, the operation and control is easy, thereby improving efficiency of system updating.

In the above technical solution, preferably, the multiple file partitions include a partition of a boot program for booting the loading of a kernel of the terminal. Detecting whether the data of the multiple file partitions specified in the system updating file has changed, and creating the identifier file specifically includes: detecting whether the data of the partition of the boot program for booting the loading of the kernel of the terminal has changed, and establishing an identifier file for updating all of systems of the terminal upon detecting that the data of the partition of the boot program for booting the loading of the kernel of the terminal has changed.

In the technical solution, the partition of the boot program for booting the loading of the kernel of the terminal is a partition which needs to be firstly loaded when the terminal is started. If the data of the partition has changed, it indicates that a system loading strategy of the terminal has changed, thus each of the systems of the terminal needs to be updated. For example, for an embedded system, e.g., the Android system, the boot program for booting the loading of the kernel of the terminal is bootloader, the partition of the boot program is an aboot partition. When it is detected that the data of the aboot partition of the system updating file has changed, it is determined that all of the systems of the terminal needs to be updated.

In the above technical solution, preferably, the multiple file partitions further include partitions of boot programs each for booting the starting of one of the systems of the terminal, and system partitions each corresponding to one of the systems. Detecting whether the data of the multiple file partitions specified in the system updating file has changed, and establishing the identifier file specifically includes: detecting whether data of the partitions of the boot programs each for booting the starting of one of the systems of the terminal has changed, and detecting whether data of the system partitions each corresponding to one of the systems has changed; upon detecting that the data of the partition of the boot program for booting the loading of the kernel of the terminal is not changed, and detecting that the data of the partition of the boot program for booting the starting of one of the systems of the terminal has changed, and/or upon detecting that the data of the system partition corresponding to the one of the systems has changed, establishing an identifier file for updating the one of the system.

In the technical solution, the partition of the boot program for booting the starting of one of the systems and the system partition corresponding to the one of the systems correspond to the one of the systems of the terminal. Therefore, upon detecting that the data of the partition of the boot program for booting one of the systems has changed, and/or upon detecting that the data of the system partition corresponding to the one of the systems has changed, it is determined that the one of the systems needs to be updated. For example, in the Android system, the partition of the boot program for booting the starting of one of the systems is the boot partition, and the system partition corresponding to one of the systems is the system partition. Upon detecting that in the system updating file the data of the boot partition corresponding to a certain system has changed, and/or upon detecting that in the system updating file the data of the system partition corresponding to the certain system has changed, it is determined that the certain system needs to be updated.

In the above technical solution, preferably, upon receiving the instruction for updating a system of the multi-system terminal, the method further includes parsing the system updating file to obtain the identifier file of the system updating file.

In the technical solution, after creating the system updating file, the system updating file is compressed is compressed. Thus, when determining whether the system updating file includes the identifier file for updating a system of the terminal, the system updating file needs to be parsed.

In the above technical solution, preferably, whether the data of each file partition has changed is determined by detecting whether each of the multiple file partitions includes a file having a specified suffix.

Specifically, in the Android system, if the data of a certain partition of the system updating file has changed, a corresponding “*.P” patch file is created in the certain partition, thus whether the data of the file partition has changed can be determined by detecting whether the file partition includes a file having the specified suffix.

In the above technical solution, preferably, the step of updating the one of the systems of the multi-system terminal includes: verifying in the system updating file files of the system partition of the one of the systems and verifying in the system updating file the data of the partition of the boot program for booting the starting of the one of the systems; after the verification, writing the files of the system partition of the one of the systems in the system updating file and the data of the partition of the boot program for booting the starting of the one of the systems in the system updating file into corresponding file partitions of the terminal respectively.

The system starting solution of the multi-system terminal of the present disclosure includes following.

According to an implementation of the present disclosure, upon receiving the instruction for starting all of the systems of the terminal, the partitions of the boot programs each for booting the starting of one of the systems of the terminal are loaded via the boot program for booting the loading of the kernel of the terminal, and scripts of init processes each corresponding to one of the systems are parsed via the init processes started by the kernel of the terminal, so as to create the file systems each corresponding to one of the systems, and start the system processes each corresponding to one of the systems, thereby realizing the loading of the system partitions each corresponding to one of the systems.

Specifically, for a dual-system terminal, one system is defined as an unsafe system, and another system is defined as a safe system. After the terminal is powered on, the boot_unsafe partition and the boot_safe partition are simultaneously loaded by the bootloader of the terminal, and the init processes are started to respectively parse the scripts of the init_unsafe and init_safe, so as to create the file systems each corresponding to one of the systems, start the system processes, and so on. Therefore, the system_unsafe partition and the system_safe partition can be loaded to finish the starting of the dual-system terminal.

As illustrated by FIG. 2, a system updating device 200 for a multi-system terminal in accordance with an implementation of the present disclosure includes a detecting unit 202 configured to detect whether data of a plurality of file partitions specified in a system updating file has changed during a process of creating the system updating file of the multi-system terminal, an establishing unit 204 configured to establish an identification file for updating a system corresponding to at least one file partition of the plurality of file partitions in the system updating file upon detecting that the data of the at least one file partition has changed, and a system updating unit 206 configured to update a corresponding system of the multi-system terminal according to the identification file of the system updating file upon receiving an instruction for updating a system of the multi-system terminal.

In the technical solution, when updating a system of the terminal, what is needed to do is to add a patch file to a corresponding file partition of the system updating file. Therefore, during the process of creating the system updating file, when it is detected that the data of the multiple file partitions specified in the system updating file has changed, the establishing unit 204 establishes an identifier file for updating a corresponding system, thus the system to be updated can be determined during the process of creating the patch file. Accordingly, when the system updating unit 206 performs an operation of system updating, a corresponding system of the multi-system terminal can be updated just according to the identifier file of the system updating file, and a user does not need to participate in the system updating process to inform the terminal of the system to be updated, accordingly, any system of the multi-system terminal can be easily updated, a high applicability can be obtained, the operation and control is easy, thereby improving efficiency of system updating.

The establishing unit 204 is configured to establish an identifier file for updating all of systems of the terminal when the detecting unit 202 detects that the data of the partition of the boot program for booting the loading of the kernel of the terminal has changed.

In the technical solution, the partition of the boot program for booting the loading of the kernel of the terminal is a partition which needs to be firstly loaded when the terminal is started. When the data of the partition has changed, it indicates that a system loading strategy of the terminal has changed, thus each of the systems of the terminal needs to be updated. For example, for an embedded system, e.g., the Android system, the boot program for booting the loading of the kernel of the terminal is bootloader, the partition of the boot program is an aboot partition. When it is detected that the data of the aboot partition of the system updating file has changed, it is determined that all of the systems of the terminal need to be updated.

In the above technical solution, preferably, the multiple file partitions further include partitions of boot programs each for booting the starting of one of the systems of the terminal, and system partitions each corresponding to one of the systems. The detecting unit 202 is further configured to detect whether data of the partitions of the boot programs each for booting the starting of one of the systems of the terminal has changed, and detect whether data of the system partitions each corresponding to one of the systems has changed. The establishing unit 204 is further configured to establish an identifier file for updating one of the systems when the detecting unit 202 detects that the data of the partition of the boot program for booting the loading of the kernel of the terminal is not changed, and detects that the data of the partition of the boot program for booting the starting of the one of the systems of the terminal has changed, and/or detects that the data of the system partition corresponding to the one of systems has changed.

In the technical solution, the partition of the boot program for booting the starting of one of the systems and the system partition corresponding to the one of the systems correspond to the one of the systems of the terminal. Therefore, upon detecting that the data of the partition of the boot program for booting one of the systems has changed, and/or upon detecting that the data of the system partition corresponding to the one of the systems has changed, it is determined that the one of the systems needs to be updated. For example, in the Android system, the partition of the boot program for booting the starting of one of the systems is the boot partition, and the system partition corresponding to one of the systems is the system partition. Upon detecting that in the system updating file the data of the boot partition corresponding to a certain system has changed, and/or upon detecting that in the system updating file the data of the system partition corresponding to the certain system has changed, it is determined that the certain system needs to be updated.

In the above technical solution, preferably, the system updating device 200 further includes a first parsing unit 208 configured to parse the system updating file to obtain the identifier file of the system updating file.

In the technical solution, after creating the system updating file, the system updating file is compressed. Thus, when determining whether the system updating file includes the identifier file for updating a system of the terminal, the system updating file needs to be parsed.

In the above technical solution, preferably, the detecting unit 202 is configured to determine whether the data of each file partition has changed by detecting whether each of the multiple file partitions includes a file having a specified suffix.

Specifically, in the Android system, when the data of a certain partition of the system updating file has changed, a corresponding “*.P” patch file is created in the certain partition, thus whether the data of the file partition has changed can be determined by detecting whether the file partition includes a file having the specified suffix.

In the above technical solution, preferably, the system updating unit 206 includes: a verifying unit 2062 configured to verify in the system updating file files of the system partition of the one of the systems and verify in the system updating file the data of the partition of the boot program for booting the starting of the one of the systems, and a writing unit 2064 configured to write the files of the system partition of the one of the systems in the system updating file and the data of the partition of the boot program for booting the starting of the one of the systems in the system updating file into corresponding file partitions of the terminal respectively after the verifying unit 2062 finishes the verification.

According to an implementation of the present disclosure, the system updating device 200 for a multi-system terminal further includes a loading unit 210 configured to load the partitions of the boot programs each for booting the starting of one of the systems of the terminal via the boot program for booting the loading of the kernel of the terminal upon receiving an instruction for starting all of the systems of the terminal, and a second parsing unit 212 configured to parse scripts of init processes each corresponding to one of the systems via the init processes started by the kernel of the terminal, so as to create the file systems each corresponding to one of the systems, and start the system processes each corresponding to one of the systems, thereby realizing the loading of the system partitions each corresponding to one of the systems.

Specifically, for a dual-system terminal, one system is defined as an unsafe system, and another system is defined as a safe system. After the terminal is powered on, the boot_unsafe partition and the boot_safe partition are simultaneously loaded by the bootloader of the terminal, and the init processes are started to respectively parse the scripts of the init_unsafe and init_safe, so as to create the file systems each corresponding to one of the systems, start the system processes, and so on. Therefore, the system_unsafe partition and the system_safe partition can be loaded to finish the starting of the dual-system terminal.

The present disclosure further provides a terminal which includes multiple systems and the system updating device 200 for the multi-system terminal illustrated by FIG. 2.

Take the dual-system terminal for an example, the following implementations will specifically illustrates the technical solution of the present disclosure in combination with FIGS. 3-7.

According to an implementation of the present disclosure, two systems of the dual-system terminal can be defined as a safe system and an unsafe system.

Wherein, the terminal can simultaneously run the two systems. The division of the system partitions is illustrated by FIG. 3. After the terminal is powered on, the bootloader simultaneously loads the boot-unsafe partition and the boot-safe partition, and starts init processes to respectively parse scripts of the init-unsafe and init-safe, so as to create file systems, start system processes, and so on. The system-unsafe partition and the system-safe partition can be loaded to finish the starting process of the dual-system terminal. The Data-unsafe partition and Data-safe partition are the data partitions for storing two systems, the recovery partition is the system backup file partition used for recovering a system.

When updating a system, the data of the aboot partition (the partition for storing the bootloader), the boot partition, and the system partition are updated. The updating is realized by installing a difference packet recording difference between an old version and a new version. Therefore, during updating a system, creating the difference packet is very important. In an actual updating process, a corresponding difference packet (that is, an updating file packet) can be created according to needs.

According to an implementation of the present disclosure, during a process of creating a difference packet, when it is detected that the data of the partition of the bootloader has changed, an identifier file update-both is created in the difference packet to indicate that the two systems need to be updated. When it is detected that the data of the boot-unsafe partition and/or system-unsafe partition has changed, an identifier file update-unsafe is created in the difference packet to indicate that the normal system needs to be updated. When it is detected that the data of the boot-safe partition and/or system-safe partition has changed, an identifier file update-safe is created in the difference packet to indicate that the safe system needs to be updated. That is, in root directory of the created difference packet (updating packet) the identifier file update-both, update-unsafe, or update-safe exists. Wherein, whether the data of a certain partition has changed can be determined by detecting whether a .p patch file exists in the certain partition. When the .p patch file exists in the certain partition, it is determined that the data of the partition has changed, otherwise, it is determined that the data of the partition is unchanged.
